Sure, adding argument parsing for this macro as well has been a prerequisite.

Then, on re-designing the list builder algorithm, I introduced linebreaks for
better readability of HTML source. While this removes the fix from [7380],
linebreaks prevent IE from running tags together inside the cloud equally well.

As a tribute to #4503 the mincount check could yield a significant speedup for
the list built by throwing (possibly many) tags with single occurrence away.
Obsolete tag list length calulation saves a few more milliseconds here.
No wait, just joking at the last one. New test in the loop eats up that gain,
and more.
